lubasha [3.4K]

<span>Answer: K = (1/2) mvÂ˛ + (1/2) IĎ‰Â˛, where m is the ball mass, I is the ball's moment of inertia (2/5)mrÂ˛, and Ď‰ is the angular velocity of the ball. Because the ball rolls without slipping, it is easy to see that v=Ď‰r, or r=v/Ď‰. Then, K = (1/2)mvÂ˛ + (1/2)(2/5)mrÂ˛Ď‰Â˛ = (1/2)mvÂ˛ + (1/5)mvÂ˛ = (7/10)mvÂ˛ Setting potential at the top equal to kinetic at the bottom, mgh=(7/10)mvÂ˛ v=âš{(10/7)(gh)} = [(10/7)(9.8)(0.51)]^(1/2) = 2.672m/s</span>

At an antique boat show, 90% of the boats are made of a natural, polished wood. 75% of the boats have some chrome accents on the

nadya68 [22]

Answer:

0.933 ; not independent

Step-by-step explanation:

Given :

A - made from natural polished wood

B - made from chrome accent

P(A) = 0.9

P(B) = 0.75

P(AnB) = 0.7

1.) probability of natural wood Giveb that it has chrome accent

P(A|B) = P(AnB) / P(B)

P(A|B) = 0.7 / 0.75

P(A|B) = 0.933

2.)

For an independent event :

P(AnB) = p(A) * p(B)

P(AnB) = 0.9 * 0.75 = 0.675

However, p(AnB) Given here is 0.7, thus the event aren't independent

Answer:

C) 120 square feet

Step-by-step explanation:

Note that the bed is in the shape of a <em>triangle</em>. You are also finding the area of the bed (Use the formula Area = 1/2(base * height)).

The base = 20, height = 12. Plug in the corresponding numbers to the corresponding variable.

A = 1/2(20)(12)

Simplify.

A = 1/2(20)(12)

A = (20 * 12)/2

A = (10 * 12)

A = 120

C) 120 square feet is your answer.

*Good luck!

ladder 5m tall when set against a wall of house just reach the window at a height 3m how far is the lower end of ladder from the

KATRIN_1 [288]

Answer:

Step-by-step explanation:

A simple matter of using Pythagoras. The hypotenuse is the ladder, and one of the legs is the wall, and we have to figure out the value of the other leg.

The Pythagorean formuda is (hypotenuse = a): a² + b² = c² (b and c are the other sides)

applying the values: a = 5 and b or c is 3 (I'll put b = 3)

5² = 3² + c²

25 = 9 + c²

25 - 9 = c²

16 = c²

√16 = c

4 = c

c = 4

there are 18 boys and 24 girls who want to participate in the trivia challenge. if each team must have the same number of boys a

Fittoniya [83]

The greatest number of teams that can enter will be 6.

The number of girls will be =2

The number of boys will be = 4

Teams within an enterprise are groups of personnel all working below a shared designation or for a shared goal. groups may be shaped in a selection of structures relying on the desires of the commercial enterprise.

working together saves time and presents each person with more strength to focus on getting the task done. with the aid of getting your employees to work as a team, you may improve the productivity levels of all and sundry present. you may actualize innovative thoughts with greater efficiency, making the importance of teamwork clean.

A clear team reason can assist motivate individuals into motion. a few advantages of understanding the purpose of a crew include growing recognition and inclusion.

The number of girls = is 18.

Number of boys = 24

Based on the information given, in order to find the greatest number of teams that can enter, we have to find the highest common factors for both boys and girls. This will be:

Factors of 18 = 1, 2, 3, 6, 9, 18.

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 16, 24.

Highest common factor = 6

Therefore, the greatest number will be 6.

The number of girls will be =2

The number of boys will be = 4
